Humminbird Helix 2GN Right Side Imaging Dark Screen

My 10” Helix recently has been a dark screen on the right side. I’ve checked and reset the Transducer Angle and inspected for cracks with none visible. I’ve checked connection pins to make sure there wasn’t one broken. The left side is still operational.
I’ve yet to reset the head unit to default and was curious if I need to save my waypoints prior to resetting.
Just looking for suggestions before I order a new transducer. Thanks for any help offered and tight lines to all.

You won't loose your waypoints when resetting defaults .... but it is always a good idea to have them backed up ... stuff happens.

Do you have another unit you can use for troubleshooting .... need to determine if the transducer or the head unit is the problem. Maybe you could test your unit on someone else's boat or the other way around.

Bob,
I wish I had that option. My front graph is a Gen 1 and different transducer. All my friends have Gen 3 units. My two units are linked so they share waypoints so I should be good there.
Just seeing if anyone else has had this issue with the grn 2 and what might resolve it.
I’ve never done a software update since the unit worked so well. Didn’t want to chance a mess up with the update. Guess my hands are kinda tied right now and I may have to do it.
Thanks for the reply.

A software update will not resolve this problem. I wouldn't do an update til you resolve it. Just one more thing to complicate the issue.

Most likely is a transducer going bad .... but could be the head unit ... you already checked connections the best you can. You could probably connect your unit to a G3 setup, but there may be some precautions to take. Maybe Rickie will check in and advise you about that.

Maybe someone else with a G2 unit will see this thread.

I appreciate the input Bob. I’ve been withholding the slush fund to purchase another unit to add to the console and now may be the time to get off the pot. At least I can still fish with a new one while the old one is possibly getting repaired at Humminbird.
I did find a transducer locally that I’m gonna try first and see if it resolves the issue.
And I’m not far from West Point lake and I may see if someone would let me hook up the unit to their transducer while on the water.

Bob gives good advice ...

Also definitely try Restore Defaults 1st ... that resolves a lot of issues ...

What is the G2N unit please ..:??

Rickie

BTW ... your update ideology is sound ...

One might not need updating unless a certain update fixes a certain gremlin -or unless the update adds a feature that the user wants ...

Dumb question.... Is your outboard in the way? My uncle has to trim his motor up some so he can see off the left side of his boat. Luckily my motor is on a jack plate so it is clear of the sonar beam.

The G2N is the second generation of Helix models that can be networked

I do have to trim the outboard up to allow clearance for the left side of SI. The right side just started messing up two weekends ago and I’ve done all the simple checks to make sure it’s not it’s all connected and plugged in. I wish I had a pic to add to the post.
The image isn’t completed blacked out. It’s shows a few feet of coverage but then goes dark.

Did you try the Restore Defaults yet?

Rnvinc, I did not get a chance to play with my unit but I did find out that my unit is still under warranty until December. I’ll post any update from resetting to default. Thanks for checking on this ole guy.

My unit quit showing the temperature. Called Humminbird and while still under warranty, they sent me a transducer. Call them. They will help.
It wasn't a transducer problem. Sent the unit back and with repairs and turn around I only lost 5 days without a unit.

Here’s the latest update.
After making contact with Humminbird and describing the side imaging issue and what I’ve already done to diagnose the problem by checking connections and cables, they want me to connect my G2N unit to the G1 transducer and see if the issue follows the head unit. Even though they are different transducers, the tech support stated it will function but not be a normal mega image. So this puts me into waiting for the weekend to check. Once it’s determined if it’s the head unit or transducer, a simple proof of purchase to show it’s still under warranty and they’ll take care of the issue.

But on a bright side, I did invest into a G3N SI unit with the ole slush fund to put me back on the water sooner. And when the G2N unit is repaired, it will get mounted in the front with the G1 unit mounted in tandem at the console just for mapping. So I got that to look toward. Thanks to all the input and I’ll post any update on the final outcome with humminbird.

So here’s the final update on the issue with the G2N unit. The circuit board was repaired by the factory and is currently on a UPS route scheduled for a Friday delivery. Whoop whoop

Thanks for all the input
